I thought he was Canadian. Was I drunk when I read that? :-)
He was born in Canada.
No, he is Canadian, but he may live in the US. I don't know about that.
In his native Canada, Mark is a columnist for The National Post, the country's leading national newspaper. In the United Kingdom, Mark appears in The Daily Telegraph, Britain's biggest-selling broadsheet daily, and The Sunday Telegraph, winner of this year's Newspaper of the Year Award.
He also writes on current events and movies for The Spectator, the oldest continuously-published magazine in the English language. In the United States, he is a columnist for The Chicago Sun-Times , America's fifth most-read daily paper, and for The New York Sun, the city's first new broadsheet daily in a quarter of a century.
Mark is also theatre critic for The New Criterion in New York. In addition, he appears in The Jerusalem Post and The Richmond Times-Dispatch of Virginia, and more occasionally in other publications, too, including The Wall Street Journal and National Review , but even when he's not in them he thinks they're worth reading, which is why we link to them here.
Mark's book on musical theatre, Broadway Babies Say Goodnight, was published to critical acclaim in the United Kingdom, and somewhat sniffier notices in the United States.
